What would be the value of the discriminant of the following?
4x2 - 2x - 8 = 0
1 answer:
Answer:
The value of the discriminant = 132
Step-by-step explanation:
4x^2 - 2x - 8 = 0
Using the discriminant
b^2 - 4ac
a = 4
b = -2
c = -8
Using the coefficients with also adding the signs before each
Insert the values
b^2 - 4ac
= (-2)^2 - 4 * 4 * (-8)
= 4 - 4 *4 * -8
= 4 - 16 * -8
= 4 - -128
= 132
The value of the discriminant is 132

Answer:
P(Sarah wins)= 1/3
P(Bridget wins)= 2/3
Step-by-step explanation:
15/45 = 1/3
1 - 1/3 = 2/3
6.75 per hour
121.50/18 = 6.75
Because of a linear pair then because of vertical angles and because all angles have to be 180 added up
